This deep dive covers Plant vs Animal Transport Systems within Plant Transport Systems for GCSE Biology. Xylem and phloem structure, water and sugar transport, root hair adaptations, translocation, and practical investigations It is section 8 of 18 in this topic. Use this deep dive to connect the idea to the wider topic before moving on to questions and flashcards.
Plant vs Animal Transport Systems
| Feature | Plants | Animals |
|---|---|---|
| Transport systems | Two separate (xylem & phloem) | One system (circulatory) |
| Transport medium | Water, sap | Blood |
| Pump mechanism | No pump (passive) | Heart (active) |
| Flow direction | One-way (xylem), two-way (phloem) | Circular (closed loop) |
| Speed of transport | Slow (meters/hour) | Fast (complete circuit in ~1 minute) |
| Substances carried | Water, minerals, sugars (separate) | Everything together in blood |
Why Do Plants Have This System?
Plants evolved separate transport systems because:
- Stationary lifestyle: No need for rapid responses like animals
- Energy efficiency: Passive transport saves energy
- Different requirements: Water needs to go up, food needs to go everywhere
- Size constraints: Separate systems work better for very tall plants
Practice questions for Plant Transport Systems
Which substance does xylem tissue transport?
Explain how root hair cells are adapted for their function.
Quick recall flashcards
What is phloem tissue?
A plant tissue that transports sugars and amino acids from the leaves to other parts of the plant.
What is xylem tissue?
A plant tissue that transports water and mineral salts from the roots to the leaves.
